  2. Direct-ethanol fuel cell - Wikipedia

    en.wikipedia.org/wiki/Direct-ethanol_fuel_cell

    The use of ethanol would also overcome both the storage and infrastructure challenge of hydrogen for fuel cell applications. In a fuel cell, the oxidation of any fuel requires the use of a catalyst in order to achieve the current densities required for commercially viable fuel cells, and platinum-based catalysts are some of the most efficient ...

  3. Fuel cell - Wikipedia

    en.wikipedia.org/wiki/Fuel_cell

    The alkaline fuel cell (AFC) or hydrogen-oxygen fuel cell was designed and first demonstrated publicly by Francis Thomas Bacon in 1959. It was used as a primary source of electrical energy in the Apollo space program. [41] The cell consists of two porous carbon electrodes impregnated with a suitable catalyst such as Pt, Ag, CoO, etc.

  4. Enzymatic biofuel cell - Wikipedia

    en.wikipedia.org/wiki/Enzymatic_biofuel_cell

    An enzymatic biofuel cell is a specific type of fuel cell that uses enzymes as a catalyst to oxidize its fuel, rather than precious metals. Enzymatic biofuel cells, while currently confined to research facilities, are widely prized for the promise they hold in terms of their relatively inexpensive components and fuels, as well as a potential power source for bionic implants.

  5. Ethanol fuel - Wikipedia

    en.wikipedia.org/wiki/Ethanol_fuel

    The technology uses heat to reform ethanol into hydrogen to feed what is known as a solid oxide fuel cell (SOFC). The fuel cell generates electricity to supply power to the electric motor driving the wheels, through a battery that handles peak power demands and stores regenerated energy.

  6. Solid oxide fuel cell - Wikipedia

    en.wikipedia.org/wiki/Solid_oxide_fuel_cell

    The planar fuel cell design geometry is the typical sandwich type geometry employed by most types of fuel cells, where the electrolyte is sandwiched in between the electrodes. SOFCs can also be made in tubular geometries where either air or fuel is passed through the inside of the tube and the other gas is passed along the outside of the tube.

  7. Microbial fuel cell - Wikipedia

    en.wikipedia.org/wiki/Microbial_fuel_cell

    Microbial fuel cell (MFC) is a type of bioelectrochemical fuel cell system [1] also known as micro fuel cell that generates electric current by diverting electrons produced from the microbial oxidation of reduced compounds (also known as fuel or electron donor) on the anode to oxidized compounds such as oxygen (also known as oxidizing agent or electron acceptor) on the cathode through an ...

  8. Alcohol fuel - Wikipedia

    en.wikipedia.org/wiki/Alcohol_fuel

    A dish of ethanol aflame. Various alcohols are used as fuel for internal combustion engines.The first four aliphatic alcohols (methanol, ethanol, propanol, and butanol) are of interest as fuels because they can be synthesized chemically or biologically, and they have characteristics which allow them to be used in internal combustion engines.

  9. Glossary of fuel cell terms - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_fuel_cell_terms

    A unitized regenerative fuel cell (URFC) is a fuel cell based on the proton exchange membrane which can do the electrolysis of water in regenerative mode and function in the other mode as a fuel cell recombining oxygen and hydrogen gas to produce electricity.
